Booting Suse 10.1 From USB External Hard Drive
Okay, first I want to point out that I am completely and entirely new to Linux; i.e., this is my first attempt at installing it, ever, and so I'm having problems.
The only computer I have available is my school laptop, and there are school/warranty issues and whatnot if I were to try and repartition the internal hard drive, so I looked around and decided to try to install it on an external USB hard drive. I heard that there were problems with booting to USB hard drives, so I chose Suse because I found a guide that kind of told me how to fix these problems for it.
So I repartitioned this external hard drive; I made a partition for NTFS, a partition for FAT32, and left the rest unallocated. I booted to the Suse 10.1 Install DVD and installed, making sure to install to the unallocated space on the external hard drive. As per the recommendation of one of the guides I installed the GRUB boot loader (I really have no idea how to use this thing, btw) to the root partition.
When Suse finished installing components, I was not in the room and when I returned, the computer was sitting at the Windows login screen. I wasn't sure if the install had worked correctly, but my unallocated space had been turned into two Linux Ext2 partitions (one of 20 GB, the other the rest of the space). Obviously, this isn't conclusive, but because I didn't return to an error message I figure that means the install went okay.
When I try and reboot the computer to the USB hard drive, the BIOS loading screen appears, pauses a second on a blank screen, the screen flickers and the BIOS loading screen appears again. This happens endlessly until I tell it to run from the internal hard drive instead. I figure this is the booting problem I was warned about where the Linux booting doesn't recognize USB devices, so the USB hard drive isn't found.
To fix this I was instructed to run in Rescue Mode from the CD and create an "INITRD Ramdisk." This is where the problem is. I put in the CD and run Rescue Mode, but I can't use the commands the guide tells me to, such as making directories because it is a "read only file system." I don't know if the fix for this is very simple or what (maybe so simple that I'm the only one foolish enough to ask about how to get around it), but I can't figure out what to do from here.
This is the brief guide I've been trying to follow, although it is for SUSE 9.2 and I'm using 10.1:
Thanks very much in advance for your help!
